Quizplus · Accepted Answer

The energy of a photon can be calculated using the formula $E = hf$, where $h$ is Planck's constant ($6.626 \times 10^{-34} \, \text{J}\cdot\text{s}$) and $f$ is the frequency of the photon. Given the frequency is $5.0 \times 10^{14} \, \text{Hz}$, the energy $E = (6.626 \times 10^{-34} \, \text{J}\cdot\text{s}) \times (5.0 \times 10^{14} \, \text{Hz}) = 3.313 \times 10^{-19} \, \text{J}$, which rounds to $3.3 \times 10^{-19} \, \text{J}$.
